CONCRETE RAILROAD TIE.

Application .filed August 11, 1924. Serial No. 731,446.

To all whom it may concern:

Be it known that I, JAKoB HoJNowsKT, a citizen of Poland, and resident of Nekoosa, in the county of d and State of Wis consin, have invented certain new and useful Improvements in Concrete Railroad Ties, of which the following is a specification.

This invention relates to improvements in railroad ties, particularly re-intorced con crete ties, and it is the main object of the invention to provide a tie which is either made in one single piece or in two pieces, whereby suitable means are pr vided to connect the pieces.

Another object of the invention is the provision of a tie made in sect-ions adapted to meet in the middle of atrack and to be secured at their meeting edges against displacement.

A "further object of the invention is theprovision of a tie of this type equipped with novel rail chairs for the footflanges of the rails and means for securing the parts firmly in place.

A still further object of the invention is the provision of atie in which a sound deadening, elastic material such as felt, etc. is interposed between the rail chair and the rail toot flanges.

It is furthermore an'object of the invention to provide a tie in which a supplementary plate is interposed between the rail foot flange, the deadening material and the rail chair.

The invention also embraces T-pieces adapted to connect the adjoining or oppo sitely disposed ends of the tie-pieces secured to the ties by suitable means, and in the provision of asuitable depression in the bottom face of the tie in which the ends of long fastening means are located.

These and other objects of my invention will become more fully known and the ad vantages obtained thereby will be further explained in the "following description and will then be fully set forth in the appended claims.

In the accompanying drawings, forming a material part of this disclosure:

Figure 1 is a side elevation of a railroad tie constructed according to the present invention.

Figure 2 is a cross-section on line 22 of Fig. 1.

Figure 3 is a side elevation of the tie with the rails and rail chairs removed.

Figure +1- is an end view thereof.

Figure 5 is a top plan view of part of a track.

Figure 6 is a side elevation of a modified form of the tie according to the present invention.

Figure 7 is a cross-section on line 77, Fig. 6. I I

Figure 8 is a cross-section on line 88, Fig. 6.

Figure 9 is a top plan view of part of a track constructed with ties according to the form illustrated in Figure 6.

Figure 10 is a top plan view of part of a track constructed with the ties according to my invention, illustrating a modification of construction.

The tie 10 of concrete or similar analogous material with inner reinforcements as for instance a wire netting 11 is provided at its ends with upper extensions forming shoulders 12 and 13 respectively, and bolt holes 1.4, 15 are arranged in the lateral faces of the tie body for the passage of bolts 16. The outer ends of these bolts extend also through the vertical. downwardly directed branches of rail chairs or brackets 17 and 18 upon which the foot flanges 19 of the rails are supported which are designated 20 in the drawings. These foot flanges rest directly upon alayer of sound deadening material 21 interposed between the foot flanges 1.9 and the horizontal branches or arms 22 ot the chairs or brackets. The customary bolts 23 equipped with fastening nuts 24 and 25 at their upper and lower ends respectively secure the foot flanges of the rails to the chairs clamping the sound deadening material firmly between them. Any suitable material, as felt, etc., may be used as sound deadening and elastic bearing layer.

In the modification illustrated in Figures 6, 7, 8 and 9, the tie is made in two pieces 26 and 27 constructed alike so that the description of one will also fitthe other. Each tie piece is made from concrete, reinforced in any suitable manner for instance as shown by a wire netting 28. A depression 29 is formed in the bottom part of each tie piece for a purpose hereafter more fully to be described. The rail chairs are formed by brackets having their vertical branches 30 connected by bolts 31 passing through these branches and the tie and bearing fastening nuts 32 at their outer ends. The horizontal branches of the bracketsare designated 33, andtheir underside is engaged by-the downwardly and reentrantly bent ends of a plate 8st, and between said plate 34 and the tie as well as the horizontal branches 33 a layer of sound deadening material 37) is interposed. Short bolts 36 carrying upper and lower fastening nuts 37 and 38 are passed through the foot flanges 39 of the rails l0, plate 34:, the layer and branches 33 to firmly hold the rails on their chairs. while longer bolts 41 carrying nuts 42 at their upper ends and equipped with heads 4-3 at their lower ends located within the depression 29 of the tie pieces, pass through the tie and the rail foot flanges. The ties have their outer ends provided with upstanding extensions forming shoulders as described above with respect to form illustrated in Figure 1, and the inner ends of the tie pieces are connected by the intermediary of a T-piece 44, through the web of which fastening bolts are passed which extend through the tie piece and carry at their ends fastening nuts 46.

While in the form of tie justdescribed, the tie pieces are placed at the proper distance from each other and are made comparatively smalL larger pieces 47, 48 are illustrated in Figure 10, which meet at their inner edges as at 9, and are connected by T-pieces 5O embedded in suitable recesses of the pieces and secured to the tie body by'means of bolts 51 to both Sides of the meeting ends provided with a head 52 atone end and securing nuts 53 at their opposite threaded ends.

It will be clear that changes may be made in the. general arrangement and the construction of the minor details such as fall within the scope of the appended claims,

without deviating from the scope and spirit of theinvention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

l. i railroad tie comprising a re-int'orced concrete body provided with upper extensions at its ends to form shoulders, brackets secured to both sides of the tie to constitute rail chairs, means for deadening the sound interposed between said chairs and the rails. and means for securing the parts in place.

2-. A railroad tie having a concrete body, a wire nettin re-intorceincnt in said body, rail chairsvhaving upperhorizontally disposed branches' and vertical branches depending at both sides of the tie in engagement therewith. bolts passed through the tie and he vertical chair branches, a layer of sound deadening elastic material between the horizontal rail chair branches and the foot flanges of the rails and means for securely holding the parts in their assembled position.

3. A re-intorced concrete railroad tie comprising a body, rail chairs secured to both sides or said body and adapted to carry the rails. a plate interposed between said chairs and rails having downwardly and re-entrantly curved ends engaging said chairs, and a layer of "felt interposed between said plate and the rail chair to deaden the sound and providing an elastic bearing face, and means for securing tie parts in their assembled positions against displacement.
